Now do the same for node02. Once the disks are seen by both guests, you can then start setting up a two-node cluster. I've used this configuration to test a two-node Oracle 10gR2 RAC setup with shared ASM storage and OCFS2 on a 64-bit system.

F. Conclusion

This kind of setup will help you to learn the basics of clustering without the need of acquiring additional hardware. In no way can this setup be used in a "live" environment. Once you have familiarized yourself with the concept of how a cluster is prepared, you can apply the concept when building real, physical setups that you need for your organization. I hope you'll find this useful.
